EXCLUSIVE: Two of the most popular Curb Your Enthusiasm recurring guest stars, husband-and-wife duo Ted Danson and Mary Steenburgen, have closed deals to return for the upcoming ninth season of Larry David’s HBO comedy. They will join the series’ core cast — David, Jeff Garlin, Cheryl Hines and Susie Essman — who also are set to come back.

Danson and Steenburgen, who play themselves, have been there from the start, making their debut on the series’ first episode after the pilot, which was titled “Ted And Mary.” Over the first eight seasons, Danson has appeared in 13 of 80 episodes, frequently butting heads with Larry; Steenburgen was in five episodes.

Both Danson and Steenburgen are regulars on other series, so the Curb gig had to be coordinated with their schedules. Danson, who stars on the NBC comedy The Good Place, as well as Hines, who stars on Fox’s Son of Zorn, are done or about done with their commitments to their full-time jobs as both new comedies were designed to produce 13-episode first seasons. Meanwhile, Steenburgen, who co-stars on Fox’s The Last Man on Earth, and Garlin, who stars on ABC’s The Goldbergs, will be working around their main gigs. (Garlin has a Curb out included in his Goldbergs contract.)

CSI alum Danson is repped by Industry Entertainment and WME. Steenburgen is repped by Management 360 and UTA.
